ATTORNEYS Filled Apr. '7, 19%, Ser- No. 20,770 17 Claims. (Cl. 26-55)This invention relates to storm windows and is a co ntinuation-in-partof my earlier application Serial No. 849,799 filed October 30, 1953,entitled, Storm Window.

In my earlier application, supra, I disclose a multisash aluminum stormwindow having many of the attributes of the two general classes ofaluminum storm windows found in the prior art, namely, the track-typeand tilt-type storm windows. The invention herein disclosed is animprovement upon that window.

In the more conventional tilt-type windows, the window frames have astepped cross section providing separate bearing surfaces for the sidesof each sash. By virtue of the stepped arrangement of the frame, thefront and rear faces of the'sash sides are not surrounded by the frameas is the case with track-type windows but rather onlythe outside faceof the sash sides are engaged by the frame. Therefore, in the absence ofspecial connectors the sashes may be lifted or drawn inwardly off theframe without any special manipulation of the sashes. Retractibleconnectors are universally provided on the sashes, which engage theframe to hold the sashes on the bearing surfaces. When these connectorsare retracted, the windows may be drawn inwardly as described. Whilethese types of windows are most satisfactory from the standpoint of easeof removal for cleaning, repairing, etc., they do not provide theprotection against the elements, which is derived from the track-typewindows,

In my prior application, supra, I disclose a storm sash having flangessecured to its sides, which extend into tracks formed in the frame toprovide the type of protection derived from track-type windows. Theflange on one side of the sash is retractible, that.is,'it may be drawninto the sash side to allow the sash to be withdrawn from the frame.Although the other flange on the opposite side of the sash is fixed, thewindow may be withdrawn by pivoting the sash through approximately fiveor ten degrees about a vertical axis defined by the fixed tates atentflange, to free the other side of the sash from the frame.

Thereafter the sash may be moved translationally in its own plane tofree the fixed flange from its corresponding sideofthe frame. 7 1

While the window disclosed in my earlier application fulfilled theobjects set forth in that application, the several manipulationsrequired on the part of the operator, as described above, to remove thesash from the frame are somewhat awkward, particularly when the sashesare large.

In the present invention, the flanges provided on each I side of thesash are retractible, that is, each may be drawn into the sides of thesashes, thus allowing the sashes to be removed in the same manner as theprior art tilt-type windows. That is, upon manipulating actuatorsconnected to the ends of the flanges, the bottom of the sash may bedrawn inwardly olf its bearing surface so that the sash lies insubstantially a horizontal plane. Thereafter, by raising one side of thesash just-a; slight amount, the connectors retaining the top of the sashon may be successively manipulated to a it lies within the side memberof the sash; FIGS. 11-14 are pictorial views suggesting the suc-' 2 thebearing surfaces maybe freed from the frame and the sash maybewithdrawn. Thus, I provide a storm window which may be manipulated withthe same ease as the prior art tilt-type windows but which neverthelessprovides the protection against the elements derived both from thetrack-type windows of the prior art and of the windows disclosed inapplicants earlier application,

' supra.

The. objects and features of my invention along with its incidentadvantages will be better understood and appreciated from the followingdetailed description of one embodiment thereof, selected for purposes ofillustration and shown in the accompanying drawing, wherein:

FIG. 1 is a fragmentary elevation view of the inside of a sash of astorm window constructed in accordance with my invention;

FIG. 2 is a cross sectional view taken along the corresponding sectionline of FIGURE 1 showing the sash assembled in a frame;

FIG. 3 is a fragmentary elevation view, partially in section, of thelower left corner of the sash, viewed from the inside;

.FIG. 4 is a detailed view of the bracket and latch mechanism used inthe upper left corner of the sash of no.1;

' FIG. 5 is a cross sectional view taken along the corresponding sectionline in FIGURE 4;

FIG. 6 is a side view of the bracket and latch mechanism shown inFIG. 4;

FIG. 7 is a cross sectional view of the bracxet and latch mechanismemployed in the lower left corner of the sash shown in FIG. 1;

FIG. 8 is across sectional view taken along the cor- I respondingsection line in'FIG. -l and rotated clockwise degrees;

FIGS. 9" and 10 are elevation views similar to FIG. 1 and; togethersuggest the manner in which the flange posltion wherein cessive stepsrequired to withdraw a sash from the frame;

FIG. 15 is a cross sectional view taken along the corresponding sectionline in FIGURE 1;

FIG. 16 is a fragmentary cross sectional view ofa sash and frame showingthe manner in which the bottom of the sash is held in the frame;

The sashshown in FIG. 1 includes an upper horizontal member 20, a lowerhorizontal member 22, a side member 24 and a glass 26 framed by theupper and lower horizontal members and the side member. While only oneside member of the sash is shown, it is to be understood that the rightside member (not shown) of the sash, is identical to and forms a mirrorimage of the side member 24 illustrated.

The top and bottom members 20 and 22 of the sash are provided withU-shaped portions 36 which receive the edge of glass 26 in a rubbergasket 31. InFIG. 15,

the cross section of the upper horizontal member 20 is I illustrated andthe U-shaped portion 30 is clearly shown, and it will be appreciatedthat the lower horizontal member 22 is merely a mirror image of the topmember.

Extending upwardly from the U-shaped section 30 of the upper horizontalmember 20 is an L-shaped portion 32 which defines with the topof theU-shaped'portion a recess 34. This recess is shaped to receive, thehorizontal arm 36 of the corner bracket 35 shown in FIG- URES 4-6.Similarly, the recess 34 provided in the lower horizontal member 22receives the horizontal portion 38 of the bracket 37 shown in FIG. 7.

The vertical side member 24 of the sash is generally H-shaped in crosssection as shown in FIGS. 2 and 8. The inner portion 40 of the H-shapedsection received the edge of the glass 26 and the gasket 31 while theouter portion 42 receives the vertical arms 44 and 45 of the brackets 35and 37 respectively, as well as the flange 46 which is substantiallycoextensive with the sash side. Thus, to connect the upper horizontalmember 20 with the vertical member 24, the horizontal arm 36 of bracket35 is slipped into the recess 34 provided in the horizontal member 20and the vertical .arm 44 of the bracket is thereafter slipped into theouter portion 42 of the vertical member. The horizontal 'arm 36 of thebracket 35 is retained in the recess 34 by the small inwardly extendinglip 50 (see FIGURE 15). When so assembled, the mitered ends of thehorizontal member and the vertical member 24 are joined together to forma continuous frame about the glass. In the same manner, the lowerhorizontal member 22 is joined with the side member 24 by bracket 37. InFIG. 6 it will be noted that the vertical arm 44 of the bracket 35 isL-shaped, and when this arm is disposed within the outer section 42 ofthe vertical side member, its plate 52 extends behind the flange 54provided as an integral part of the side memher to prevent that leg fromslipping out of the side member. The inwardly extending lip 56 whichnarrows the opening into the outer section 42 of the side member furtherserves to retain the vertical arm 44 ofbracket 35 in position.

Formed as an integral part of the corner bracket 35 is an outwardlyextending pin 60 which extends upwardly through a slot (not shown)formed in the end of the top face of L-shaped section 32 of upperhorizontal member 20. This pin 60 as is explained in detail below,serves to retain the top of the sash within the window frame independentof the flange 46. Disposed parallel to the pin 60 and extending throughthe horizontal arm 36 of the corner bracket 35 is a latch 62 having athumb grip 64. The latch 62 is free to slide within limits through thehorizontal arm 36 andis guided along its; path by the three sides 66, 68and 70 of that arm. The latch 62 carries a downwardly extending boss 72which engages a latch. However, this frictional retardation of themovernent may readily be overcome by actuating the latch by means of thethumb grip 64. Referring to FIGS. 1 and 4, the reader will recognizethat when the latch 62 is moved to the-right as viewed in those figures,the boss 72 engaging the notch 74 in the flange 46 will carry thatflange to the right into the recess of the outer portion 42 of the sidemember 24.

A latch 80 substantially identical to the latch 62 is slidably mountedwithin the horizontal arm 38 of the lower corner bracket 37. The latch80 has an enlarged head 82 formed at its outer end and is provided witha recess 84 in its mid-portion which houses a spring 86. One end of thespring 86 bears against the latch itself while the other end engages ashoulder 88 formed at the right end of the horizontal arm 38 of thebracket 37. Thus, the spring 86 urges the latch 80 to the left as viewedin FIG. 7. In FIG. 1 it will be noted that attached to the enlarged head82 of the latch 80 is a boss 90 disposed within a notch 92 formed in thelower end of the flange 46. Thus, while the latch 62 controls theposition of the upper end of the flange 46, the

latch controls the position of the lower portion of the flange.Moreover, while the upper portion of the flange 46 may be disposed inany selected position without retaining control of the latch 62, thelower portion of the flange 46 is biased to an extended position andonly by retaining control of the latch 89 may the flange be held in anyother position.

It will be noted in FIGS. 2 and 8 that the flange 46 is loosely fittedwithin the outer portion 42 of the H-shaped vertical side member 24.Because the flange 46 is loosely disposed within that section, it isdesirable to provide the flange 46 with a non-metallic coating such asrubber to prevent rattling. It is most desirable that the flange 46 fitloosely within the opening. in the vertical member for if the flange hada'snug fit therein, any dirt which collected within that outer portionof the sash side would cause the flange to bind and make actuationdifficult.

In FIGS. 9 and 10, I have illustrated the manner in which the flange 46may be withdrawn into the vertical side member 24 of the sash. Theseviews coupled with that of FIG. 1 illustrate three positions of theflange. In FIG. 1 it will be noted that the flange 46 extends anappreciable distance outwardly beyond the edge of the side member 24. Todraw the flange 46 into the vertical member, the upper latch 62 shouldfirst be pulled to the right. When so actuated, the upper end of theflange 46 is drawn totally within the member 24 as shown in FIG. 9. Itwill be noted in that figure, however, that the pin 60 which isintegrally formed with the bracket 35 does not move. To complete thewithdrawal of the flange 46 into the vertical member 24 of the frame,the operator must move the lower latch 80 to the right as suggested inFIGURE 10. This action not only completely draws the flange 46 into theside member 24 but in addition 'draws the head 82 of the latch 80m aposition wherein it does not extend outwardly of the outer edge of thatvertical side member. It will be appreciated that the identicalstructure described is found on the other vertical side member (notshown) of the sash. Thus, both flanges movably mounted along the sidesof the sash may be drawn within the side members when actuated in themanner suggested in FIGS. 9 and 10.

Having described the details of the sash, I will now describe the mannerin which the sash is assembled in the window frame. In FIG. 2 a crosssection of one side 1000f the frame is shown. This side may be made ofaluminum and extruded in long sections and later cut to the properlength. The side 100 includes an outwardly extending flange 102 whichmay be attached by an conventional means to the permanent window casing.When so mounted, the inner surface 104 lies against the outer face ofthe casing and thus, the sash which is shown in part in that figure isspaced asubstantial distance from the permanent window (not shown). Theside member 100 of the window frame is provided with four panels 106, t

108, and 112 oriented in a stepped afrangmcnt the center of the completewindow frame, (to fight as shown in FIG. 2) beyond the inner edge ofpanel 1 and similarly, panel 110 extends inwardly beyondpalifi 108,'andpanel 108 in turn extends inwardly beyond panel 106. The inner face ofeach panel, and more particularly that portion of each panel whichextends inwardly beyond the end of the next inner panel, serves as abearing surface for the side members of the sash. Thus, the innersurface 114 of the panel 112 serves as a bearing surface upon which theside member 24 of the sash shown rides up and down within the frame. Theother side member (not shown) of the sash rides on an identical bearingsur face formed on the other side of the frame (not shown) to provide afirm backing support for the assembly. Disposed in a recess 116 on theouter surface of the side member 24 of the sash is a length of weatherstripping 118 forming a seal between the outer surface of the sidemember 24 and the bearing surface 114..

The inner edge of each of the panels 106, 108 and 110 carry an outwardlyturned lip 120, 122 and 124 respectively, which serve to guide the edgesof the side members 24 and prevent the sashes from shifting laterally onthe bearing surfaces. It will be noted in FIG. 2 that the side member 24of the sash does not extend into the space between the panels llti and112 but rather is prevented from doing so by the lip 124. t

In the conventional tilt-type windows found in the prior art, the upperportions of the side members of the sashes are retained on the bearingsurfaces by the type ate the two latches at the top corners of the sashas suggested in FIG. 11 to move the flanges 46 to the position.

shown in FIG. 9. Because the latches are not biased to a particularposition, the flanges will remain in that posi V latches in thewithdrawn position, the flanges 46 will re-.

of pins as suggested at 50 which extend outwardlyfromthe sides of thesashes into the spacebetween the; panels 11%) and 112 and bear againstthe outer edgeof the lip 124. The heads 82 forming part of. the latchesin the lower corner brackets similarly" bear against the outer edges ofthe lips 124 on each side of the frame to retain the lower portion ofthe sash on the bearing surfaces. Thus, to remove the sashes of theprior art tilt-type windows from the frame, it is necessary to actuatethe latches on the bottom of the sash to free the bottom of the sashes,and hereafter, by tilting the sashes the pins 60 may be removed ordisengaged from the outer edges of the lip 124. This is suggested in thepictorial views of FIGS. 12-14. A cross section of the frame and sidemember of a sash of the prior art tilt-type windows would be similar tothe cross section shown in FIG. 2 without the flange 46.

From this description of the prior art it will be recognized that onlythe upper and lower extremes of the side members of the sash are firmlyheld against the bearing surfaces and no mechanical means isincorporated to urge the intermediate portions of the side membersagainst those surfaces and'form a track-type connection between the sashand frame. Thus, any warping of theside members or distortion of thosemembers under the influence of pressure applied totheir outer surfacesmay readily move the intermediate or central portions of the sidemembers off the bearing surfaces to create an opening through which airmay flow. As in my earlier applications, supra, the flange 46 isprovided to prevent this. Any distortion, bending or warping of the sidemembers will cause the flanges 46 to bear against the outer edges of thelips 124 and form a virtual seal about the side edges of the sidemembers to prevent air from flowing around the sashes to the interior ofthe storm window. The flanges 46 which under normal conditions fitloosely between the adjacent panels of the frame and may readily bemoved up and down with the sash, and as well, may be moved into the sidemembers 24, nevertheless, are available to form the weather seal whenrequired.

' While in FIG. 2 but onesash is illustrated, it should be understoodthat a second window sash will ride on the inner face of the panel 110and bear against the lip 122.

A third sash normally carrying screening will ride on the inner surfaceof the panel 1% and its edge will bear against the lip 12%. The twoadditional sashes not illustratedin FIG. 2 will have side memberssubstantially identical to those illustrated and include the flanges 46which normally extend between their bearing surfaces and the next innerpanels.

The advantages of having each flange on the sash movable as opposed tothe arrangements suggestedin my earlier application, supra, will bedescribed indetail in connection, with FIGS. 9-14. When but one of theflanges is movable,- a rather awkward manipulation is required on thepart of the operator to remove the sash from the frame. However, thesash with the two movable flanges may but with one additionalmanipulation on the part of the operator be removed in the same generalmanner as the tilt-type windows of the prior art.

Assume that the sash shown in FIG. 1 is disposed within the window frameand its flanges on each of its side members extends out of the sidemembers and into the space between the adjacent panels of the frame asin FIG. 2. To remove the sash, the operator will first actu mainin theposition shown in FIG. 10 within the side members of the sash. At thesame time, the heads 82 formed on the extremities of the latches will bedrawn a into the side members and off the outer edges of the lips on theends of the panels of the frame. Therefore, the operator while holdingthe latches in the withdrawn position may swing the window sash inwardlyat its bottom. When so moved, only the pins which bear against the outeredges of the lips of the frame have any connection with the frameitself. Having moved the bottom of the sash inwardly a sufficientdistance to free the heads 82 from the window frame, the operator maythen release the latches, and grasp the sash in the manner suggested inFIG. 13. Thereafter, the sash may be removed by lifting one side assuggested in FIG. 14.

To remount the sash within the fra me, the sequence of steps need onlybe reversed. Thus, the operator first positions the pins 66 within theadjacent panels in the manner shown in FIG. 14-and then retracts thelatches 30 at both of the bottom corners until the sash lies flushagainst its bearing surfaces. 'Thereafter, upon release the latches atthe bottom of the sash, the heads 82 pass .into the space bettween theadjacent panels and engage the outer edges of the lips. When this isdone, the flanges 46 liein the position shown in FIG. 9. Thereafter,when the sash is mounted, the operator should outwardly ac-,

tuate the two latches 62 at the top of the sashes to move the flanges 46to their fully extended position wherein they lie throughout theirlength within the space between the adjacent panels. Having so actuatedthe flanges 46, it will provide the protection sought about the edges ofthe vertical side members of the sash.

Theheads 82 formed on the latches 37 perform one additional function notpreviously mentioned. That is, not only do they serve to retain thelower portion of'the sash against the bearing surfaces but in additionserve to hold the sash in selected raised positions within the frame.This is accomplished by forming a series; of spaced notches (not shown)on the outer edges-of the lips 120, 122 and 124 which receive the heads82. When the heads register with su'ch notches, it is necessary to is myintention that the breadth of this invention be de termined by theappended claims and their equivalents.
